More Information
Summary:A pixel capable includes an organic light emitting diode (OLED) coupled between first and second power sources, and a pixel circuit coupled between the first power source and the OLED to control driving current supplied to the OLED. The pixel circuit includes a first transistor with a first electrode coupled to a data line, a second electrode coupled to a first node, and a gate electrode coupled to a current scan line, a second transistor with a first electrode coupled to the first power source via the first node, a second electrode coupled to the OLED, and a gate electrode coupled to a second node, a first capacitor coupled between the first power source and the second node, and a second capacitor coupled between the second node and the current scan line. An aperture is formed in at least one electrode of the two electrodes of the first capacitor.
